Duphamox 150 mg/ml Suspension for Injection.


Duphamox is an off-white suspension for injection containing 150 mg of amoxicillin (as Amoxicillin Trihydrate) per ml. Each ml also contains Butylhydroxyanisole 0.08 mg and Butylhydroxytoluene 0.08 mg as antioxidants.


Duphamox is indicated in the treatment and control of infections caused by organisms sensitive to amoxicillin.

Amoxicillin is a broad-spectrum semi-synthetic penicillin bactericidal in action. In vitro it is effective against a wide range of Gram-positive and Gram-negative bacteria which include:

Actinomyces bovis, Actinobacillus equuli, Actinobacillus lignieresi, Bacillus anthracis, Bordetella bronchiseptica, Clostridium spp, Corynebacterium spp, Erysipelothrix rhusiopathiae, Escherichia coli, Fusiformis spp, Haemophilus spp, Moraxella spp, Pasteurella spp, Proteus mirabilis, Salmonella spp, Staphylococci and Streptococci (non-penicillinase producing) in cattle, sheep, pigs, dogs and cats.

Dosage and administration

Shake well before use.

Administration is by the intramuscular route for cattle, sheep and pigs and by the intramuscular or subcutaneous route in dogs and cats. The dosage rate is 7mg/kg bodyweight daily for up to 5 days (equivalent to 0.25ml per 5kg daily). Massage the injection site after injection.

The suggested dosage rates are


450 kg

20.0 ml


65 kg

3.0 ml


150 kg

7.0 ml


20 kg

1.0 ml


5 kg

0.25 ml


Normal aseptic precautions should be observed. Use a dry syringe for extraction of suspension to avoid hydrolysis of amoxicillin.

If dose volume exceeds 20 ml in cattle or 10 ml in sheep and pigs, it should be divided and injected into two sites.

A separate injection site should be used for each administration.

An appropriately graduated syringe must be used to allow accurate administration of the required dose volume. This is particularly important when injecting small volumes.
